I have a friend who uses one and have tried it. Great tasty vape but it seems pretty advanced and certainly Not for the noobs (me). Def let us know your results if you order one...

Here's a bit more info I found:

No longer are precision screw drivers needed to disassemble and install new coil and wick. Simply coil your wick and insert your coil in the poles, snap on to the posts of the Eternity, then trim your coil and you are ready to vape in either of two ways: Use a traditional dripping method with one BIG difference - this will take up to 40 drops of eLiquid. Or you can use an ego-c or ego-t style tank with the included extra cone. A much improved piercing rod makes a larger hole and provides other technology that works very very well as opposed to the foibles many experience with a regular ego-t set-up.

VISION has worked long and hard to make the ULTIMATE Rebuildable Atomizer! Both in design, packaging, testing and development in a high quality-assured environment. The quality and beauty you see in the product and packaging reflects the dedication VISION has had towards this product.

The VISION Eternity is made of quality, highly polished chrome plated pure brass and included in your 6 piece set up is a beautiful ribbed eGo sleeve cover you can use optionally at the base that threads onto your outside eGo threads.
